A possible mechanism for QPOs modulation in neutron star sources
It was pointed out by Paczyński (1987) that the X-ray luminosity of accreting neutron stars is very sensitive to the physical properties of the accretion flow close to the innermost stable circular orbit. The X-ray radiation is dominated by that emitted in the boundary layer, where accreted matter hits a star surface. The X-ray luminosity of the boundary layer is proportional to the local accre...
متن کاملTerrestrial Planet Formation in Binary Star Systems
More than half of all main sequence stars, and an even larger fraction of pre-main sequence stars, reside in binary/multiple star systems [1, 2]. Numerical simulations of the collapse of molecular cloud cores to form binary stars suggest that disks form within binary star systems [3]. The presence of disk material has been indirectly observed around one or both components of some young binary s...
متن کاملImplications of Binary Properties for Theories of Star Formation
The overall frequency and other statistical properties of binary systems suggest that star formation is intrinsically a complex and chaotic process, and that most binaries and single stars actually originate from the decay of multiple systems. Interactions between stars forming in close proximity to each other may play an important role in the star formation process itself, for example via tida...
متن کاملPossible explanation for star-crushing effect in binary neutron star simulations
A possible explanation is suggested for the controversial star-crushing effect seen in numerical simulations of inspiralling neutron star binaries by Wilson, Mathews and Marronetti (WMM). An apparently incorrect definition of momentum density in the momentum constraint equation used by WMM gives rise to a post-1-Newtonian error in the approximation scheme. We show by means of an analytic, post1...
متن کاملSupernovae in Helium Star–Neutron Star Binaries: A Possible γ-ray Burst Mechanism
Helium star–neutron star binaries are widely believed to be the progenitors of the observed double pulsar systems. In these, the second neutron star is presumed to be the compact remnant of the helium star supernova. Here, the observational implications of such a supernova are discussed, and in particular are explored as a candidate γ-ray burst mechanism. In this scenario the supernova results ...
